Double side friction stir welding effect on mechanical properties and corrosion rate of aluminum alloy AA6061

“…High welding speed has a major influence on the mechanical properties of welding nuggets [ 33 ]. The presence of high heat due to friction and non-uniform cooling rate affects the corrosion rate, this heat causes metallurgical transformation in all areas of the Heat Affected Zone (HAZ) and weld metal (WM) [ 12 ]. The difference in microstructure depends on the cooling rate and peak temperature in each region, so the corrosion behavior can be very different for each area of the weld.…”

“…The working principle of this welding utilizes the rotation of the tool into the workpiece which produces heat due to friction between the tool and the workpiece or metal to be joined until the metal side softens. The presence of high heat due to friction and non-uniform cooling rate affects the mechanical properties and corrosion rate, the heat causes metallurgical transformation in all areas of the Heat Affected Zone (HAZ) and weld metal (WM) [ 12 ]. To get a connection that has good quality is not easy, because you have to pay attention to the parameters on the Friction Stir Welding (FSW) adjusted to the material to be joined.…”
